1) What is the direction of electric current in an electric circuit ?
2) what do you mean by Electricity ?
3) How does an electric bulb glow ?
Answers
Answer:
From higher potential to lower potential
Energy due to flow of current
Bulb glows due to current passing through a wore of special material which is laminated by a special gas in bulb.
Answer:
1 )The direction of an electric current is by convention the direction in which a positive charge would move. Thus, the current in the external circuit is directed away from the positive terminal and toward the negative terminal of the battery. Electrons would actually move through the wires in the opposite direction
2)a form of energy resulting from the existence of charged particles (such as electrons or protons), either statically as an accumulation of charge or dynamically as a current
3)The filament of an electric bulb glows because of the heating effect of electric current. As the current passes through the bulb it heats the filament which gives off light. ... The filament then heats up and becomes red-hot as a result of this it begins to glow, turning electrical energy into light energy.
